IMPROVEMENT IN PRESSES FOR PR ESS ING YARN, 8w.

i To all whom it may concern:

Be it known that I, THOMAS Srrnns, of Wooster, in the county of Wayneand State of Ohio, have invented a new and improved press, which isespecially designed for pressing yarn but may be employed for otherpurposes; and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawingwhich forms a portion of this specification, of which- Figures 1 and 2are side elevations, representing diiferent positions of thelaterally-movable as Y well as vertically-movable platen of the press;Fig. 3, an end view of said press; and Fig. 4, a

top view of the same.

An open frame-work, of the shape shown in the drawing, constitutes thebody of my said improved press. the base platform a, the verticaluprights or ribs b b b b b and 0 c c c c, which rise from opposite sidesof said platform, and the horizontal arms or ways d d, which projectoutwardly from the uprights b c, as shown in Fig. 1. The upper ends ofthe uprights or ribs 1) b, c c, 850., are all brought to the samehorizontal plane with the upper edges of the arms or ways at d; and therespective series of said uprights are also in line with the arm d,which projects from the right-hand upright of each of said series. Ametallic carriage, c, of such a shape that its 1 sides will rest uponand pass a short distance within the inner sides of the upperends of ther respective series of uprights b b, c c, &c., is placed upon the frameof the press, and may be freely moved to and from the various positionsrepresented in the drawing. A vertical screwaperture in the centralportion of the carriage e receives the screw f, whose lower end isswiveled to the platen g, which plat-en works freely between the innersides ofthe series of frame uprights or ribs 1) b, c c, &c., as shown inFig. 3.

I prepare my improved press for the free reception of the yarn to bepressed by first screwing the platen 9 up. to its highest position; thenrunning the carriage e and the platen g out upon the arms or ways (1 dto about the position shown in Fig. 2; and then placing the tie-ropes gg through the open spaces between the up rights or ribs 1) b c 0 intothe transverse grooves in the platform a. After the requisite quantityof yarn has been placed within the space above the platform a therequisite tie-ropes are placed Said frame-work consists of transverselyabove the same through the spaces between the respective uprights b b,850., and c c, 860., and then the carriage e and the platen g are runinward until the lugs h h, which laterally project from opposite sidesof said carriage, are carried under the retaining heads of the holdfastsor hooks i '6, which hold-fasts rise from and are secured to or form aportion of the central uprights or ribs b c of the frame-work of thepress, as shown in Figs. 1 and 2; then, when thus prepared, the platen gis forced downward by the application .of the requisite degree of powerto the rotation of the screw f. After attaining the requisite degree ofpressure upon the contents of the press, and after properly securing theends of the tie-ropes to each other, the platen g is moved upward by are verse movement of the screw f, and is then run outward upon the armsor ways 01 d preparatory to the removal of the pressed bale and thereception of the requisite material for the formation of another bale orpackage by a repetition of the same operation as that above set forth.The lugs j j, that rise from the outer ends of the frame arms at d,serve as guards to prevent the carriage g from being run out too farupon said arms.

I propose to sometimes elongate the framework, swivel, and multiply thehold-fast-s z iof my improved press to such an extent as shall enablethe press to receive two or more distinct charges of yarn or othermaterial, to be pressed one after the other by one and the same platen.

I claim as my invention-- 1. The open body of the within-describedpress, consisting of the platform a, the uprights or ribs I) b c c, thehold-fasts or hooks i c, and the horizontal arms or ways 01 d, arrangedsubstantially as and for the purpose set forth.

2. The combination of the jointly-acting carriage 0 provided with lugsh, the screw f, and the platen g with the uprights or ribs 1) b c a,horizontal arms or ways at d, and the hold-fasts or hooks i 'i, of thebody portion of the press, substantially as and for the purpose setforth.

In testimony that the foregoing is a full and clear specification of mynew and improved press for compressing yarn, 850., I hereunto subscribemy name.
